Mandatory evacuations were issued Tuesday night in downtown San Anselmo, as a nearby creek approached flood levels, according to the Central Marin Police Authority and the Marin County Sheriff's Office.

Central Marin police were aiding in the evacuations, driving their cruisers up and down streets with lights and sirens running and ordering people in businesses and residences to leave the downtown area.

San Anselmo was one of the areas in Marin County that was under a flash-flood warning since early Tuesday.

Elsewhere in Marin County, Novato police recommended evacuations Tuesday evening for Nave Court, Lauren Avenue and Joan Avenue, near Novato Creek. But after the water receded, the advisory was lifted just after 9:30 p.m. and the evacuation center at Margaret Todd Senior Center closed later Tuesday night.
